When did you start working hard?

I began to work hard after I failed in the college entrance examination. I really envy those who were born with golden spoons. At that time, I felt that I was a little inferior to others, and I felt that I could not compare with others no matter how hard I worked, but I also wanted to understand it later, because I found that my efforts were still rewarding. Since the starting point is not as high as others, we must work hard the day after tomorrow. There is a saying that hard work may not be rewarded, but no hard work will not be rewarded.
